STORAGE Those valves not destined to immediate use will be adequately protected and packed before shipping in such away as to avoid any possible damage during transport and during the subsequent storage period before use.It is recommended that the valves remain in their own packing cases during the entire period of storage. To prevent damage to the raised faces and accumulation of dirt inside the valve, the end caps must not be removed.The valves must always remain in the FULLY OPEN position. The valves should be stored in weather proof/watertight environment.Gears and actuators are shipped ready-mated to their respective valves together with associated accessories.Caution must be taken to ensure that caps, plugs etc.protecting against dust, sand, or other foreign particles through the air inlet ports, hydraulic fluids or electric wires,are not removed until installation. INSTALLATION CAUTION : BEFORE INSTALLATION OF THE VALVES IT IS VITAL THAT ALL CONNECTING PIPING IS COMPLETELY CLEAN AND FREE OF DEBRIS , RESIDUES FROM WELDING , CALAMINES , ETC ., WHICH COULD DAMAGE THE BALL AND THE SEATS . THE VALVE MUST BE KEPT IN THE FULLY OPEN POSITION DURING INSTALLATION AND THE PROTECTIVE END CAPS MUST NOT BE REMOVED UNTIL THE LAST MINUTE . THE PIPING MUST BE STRESS FREE TO AVOID REACTION FORCES ON THE VALVE . At the shipping stage the valves are usually protected from corrosion with MOBILGREASE HP 222. Please verify grease compatibility with operating conditions and fluids used during plant starting up. On carbon steel valves, some oil can be applied in order to prevent internal parts corrosion: if required, oil and grease can be easily removed before use through a solvent.The valves must be lifted and handled using the adequate eyebolts, or better, ropes or bands positioned under the valves, close to the two end flanges, according to the schemes 1,2 and 3 of Fig. 1 of the drawing DWG.63-98 rev2. The ways 4 and 5 of the Fig. 2, on the contrary, are to be avoided.Dafram Ball valves are suitable for installation with actuators fitted when they are installed with the valve stem in the vertical position. If installation of Dafram Ball valves fitted with actuators is to be carried out with the valve stem in a different position other than vertical, then contact should be made with Dafram Technical department to verify the suitability of the installation and advise regarding the use of proper supports for the actuators. Please note that when bare stem valves are supplied, Dafram cannot be held responsible for any sizing of lifting points or valve and actuator supports when these are required by the client,unless full details regarding the size, type and wei ght of the actuator to be used are provided together with details of the valve and actuator installation/assembly. 查看更多7个回答 . 5人已关注
